UNTWISTING DEVICE.

,. Application filed June 2, 1922. Serial no. 565,413.

7 To all whom it may concern Be it known that 1, WILLIAM E. PUTNAM, a citizen of the United States of America, and resident of Weston, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Untwisting Devices, of which the following is a specification.

This invention relates to untwisting devices, particularly adapted for use on portable electrical instruments such as telephone instruments which have a conductor cord carrying the electrical connection, this cord being attached to the portable instrument at one end and to a fixed support at the other.

In use the cord becomes twisted to the annoyance of the user of the instrument. Not only do the kinks produced by the twisting of the cord greatly shorten the latter, but they also-prevent or interfere with the moving of the instrument by catching on, behind and beneath furniture anywhere near. Furthermore the sharp bends produced in the cord tend to break the wires and cause imperfect and impaired transmission of the electrical impulses. The twisting of the cord is most annoying when long cords are used.

Objects of the invention are to' provide an electrical instrument withmeans for easily untwisting the cord attached thereto thereby to render such instruments more easily moved, and in general to obviate entirely or greatly lessen the annoyance and impaired service encountered in the use of such instruments.

For the purpose of more clearly disclosing the invention, one concrete embodiment thereof is illustrated in the accon'ipanying drawings, in which:

Fig. 1 is a side elevational view;

Fi 2 is a rear elevational view, and

Fig. 3 is a detail view of the upper portion of Fig. 2, certain of the parts being shown in section.

The embodiment of the invention shown for the purpose of illustration comprises a portable telephone instrument of usual form having a base A, a standard B, a mouth piece C attached to the upper end of the standard by the usual bolt and nut connection D, and a hook E supporting the receiver F. A flexible cord G of the usual type enters base A to make the electrical connections to the receiver and the mouth pieceo In order to permit an instrument of'st-he type shown to be rotated'tountwistthecord suitable apparatus isprovidedwhich may.

comprise a handle H connected to the in" through bolt D by which the member is securely fastened to the upper end of the instrument preferably upon the side above hook E. The upper end of member I provides a vertical disposed opening through which the lower end of handle H may er;- tend to form the swivel connection. One method of producing the opening is to pro vide loops K upon the free ends of the memher I, the loops being disposed in alinement as indicated on the drawings with the shank L of the handle H extending the-rethrough and headed over at M to secure the parts together. An annular projection or shoulder N may be provided upon shank L above loop K to retain handle H in proper position.

YVith the apparatus disclosed it is possible to readily untwist the cord G when desired. the method being to lift the instrument by grasping handle H and then rotating the instrument upon the shank L as a pivot, this movement of the instrument being possible by the provision of the swivel con nection between the handle and member I. The handle further provides convenient means for moving the instrument from one place. to another.

I claim:

1. In combination, a portable telephone instrument having a mouth piece at one end and a cord attached to the other end, a member removably attached to said in strument by means of the bolt for said mouth piece, and a handle having a swivel. connection to said member whereby said instrument may be held suspended by said handle and rotated thereon to untwist said cord.

2. A swivel handle for a telephone instrument of the type having a mouth piece pivotally attached to a stand, comprising a connecting member having an opening to receive. the pivot bolt of the mouth piece, and a handle having a swivel connection to said member. whereby an instrument may be suspended by the handle and rotated thereon to untwist the telephone cord.

3. A swivel handle for a telephone in connecting member in the form of a loop of 15 wire, the loop being bent inwardly near one end to form a shoulder adapted to position the loop on the pivot bolt of the mouth piece with the bolt between said shoulder and said end of the loop, and a handle having a swivel connection to said member, whereby an instrument may be suspended by the handle and rotated thereon to untwist the telephone cord.

Signed by me at Boston, Mass, this 31st 25 day of May, 1922.

WILLIAM E. PUTNAM.
